Sunxi support

Current status

Tips, Tricks, Caveats

Adding a serial port (voids warranty)

WARNING: Do not attach VCC like the person who made this picture. This might harm your device.

Disassembling the device

Provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped.

Locating the UART

There are 2 pads labelled "RX" and "TX" between the SoC area and the GSM/GPRS module. You can get Ground from anywhere else on the board. All you have to do is follow the UART howto to solder on some wires.
